Definitions

  • the present invention relates to an electronic ballast for operating at least a first and a second discharge lamp with a bridge circuit comprising at least a first and a second electronic switch, wherein the input of the bridge circuit is coupled to a DC supply voltage, wherein the output of the bridge circuit with a first terminal for a first discharge lamp and a second terminal for a second discharge lamp, wherein the first and second terminals are connected in parallel with respect to the output of the bridge circuit, at least one first and one second ignitors, one in series with the other Discharge lamp arranged inductance and arranged parallel to the respective discharge lamp capacitance comprises, a current measuring device which is designed to provide at its output a signal with the actual value of the total current through the least ns first and second inductance is correlated, and a drive circuit.
  • the latter has at least a first and a second output for driving at least the first and the second electronic switch, a first input, which is coupled to the output of the current measuring device, a Schwellwertvorgabevorraum for specifying at least a first threshold value for the total current through at least the first and the second inductance, wherein the drive circuit designed is to control at least the first and the second electronic switch, taking into account the first SChwellwerts as a setpoint. It also relates to a method for operating at least a first and a second discharge lamp on such an electronic ballast.
  • the present invention relates in particular to the problem that high and low pressure discharge lamps for ignition require high voltages. These voltages are generated by electronic ballasts using a series resonant circuit. In two- or multi-lamp electronic ballasts often two or more parallel load circuits are used. In the case of two-lamp electronic ballasts, by means of which the following invention is described by way of example, therefore, the bridge circuit must be designed for twice the current as in the operation of a single discharge lamp. Usually, both load circuits do not have exactly the same resonant frequency. This can cause one discharge lamp to fire earlier than the other. If this happens, the current in the load circuit with the ignited discharge lamp becomes significantly smaller.
  • an ignition controller provided in the electronic ballast still allows twice the current compared to the ignition of a discharge lamp, this current then being largely due to the unloaded, ignited load circuit. flows. As a result, significantly higher ignition voltages are generated in this open circuit than desired.
  • the present invention is therefore the object of developing an aforementioned electronic ballast or an aforementioned method such that a dimensioning of the components involved for lower voltages is possible.
  • the present invention is based on the finding that this object can be achieved if the electronic ballast further comprises an ignition detection device for detecting whether one of the discharge lamps has ignited.
  • the drive circuit comprises a second input which is coupled to the ignition detection device, wherein the threshold value setting device is further designed to specify a second threshold value for the setpoint value of the total current through at least the first and the second inductance, wherein the second threshold value is smaller in magnitude than the first one threshold.
  • the drive circuit is configured to drive at least the first and second switches before detecting the ignition of a discharge lamp by the ignition detection device as the target value after detecting the ignition of a discharge lamp by the ignition detection device in consideration of the second threshold value.
  • a preferred embodiment is characterized in that the drive circuit further comprises a comparator which is designed to compare the actual value of the total current through at least the first and the second inductance with the respective desired value of this current.
  • a comparator for example, the microcontroller AT90PWM2 the company Atmel can be used. By using a comparator, compliance with the setpoint can be monitored very closely. This makes it possible to realize a precise, cost-effective dimensioning of the components involved.
  • the ignition detection device comprises a power measurement device configured to determine a magnitude correlated with the power output at the at least first and second ports.
  • the measurement of power provides a more reliable indication of whether one of the involved lamps has ignited or not.
  • the drive circuit is designed, the actual value of the total current by varying the frequency of the signal, with which at least the first and the second electronic. Switches are controlled to regulate.
  • the drive circuit is furthermore preferably designed to control the frequency of the signal with which at least the first and the second electronic switches are actuated be further lowered after detecting the ignition of a discharge lamp. This procedure is described in the applications ⁇ WO 2008/037290 A1 and EP1871147 A1 ,
  • the drive circuit of an electronic ballast according to the invention is in particular designed so that a changeover from the first to the second threshold value in a period of time which is a maximum of 1 ms, preferably a maximum of 200 ⁇ s, can be made.
  • the wording "taking into account the first or second threshold” takes into account the fact that in practice a slight exceeding of the respective threshold value may occur, since only the current through the lower electronic switch when the bridge circuit is implemented by a half bridge is evaluated for the current measurement becomes.
  • the second threshold value is at most 80%, preferably at most 75% of the first threshold value.
  • Fig. 1 shows a schematic representation of the structure of an electronic ballast according to the invention for operating a first La1 and a second discharge lamp La2.
  • the ballast comprises a first E1 and a second terminal E2 for connection to a mains voltage U N.
  • a block 10 which includes a rectifier and components for EMC protection.
  • a boost converter 12 which comprises an inductance L1, a switch S1, a diode D1 and a capacitor C1.
  • the so-called intermediate circuit voltage U zw is provided on the one hand to a voltage divider R1, R2, on the other hand to the two switches S2, S3 of a half-bridge.
  • the signal picked up at the resistor R2 is supplied to a unit 14 of a microcontroller 16, the unit 14 serving for PFC (Power Factor Correction).
  • the switch S1 of the boost converter 12 is actuated in a manner known to the person skilled in the art with regard to the magnitude of the voltage U zw sensed by the resistor R2.
  • the switches S2, S3 of the half-bridge are controlled via a drive generator 18 of the microcontroller 16.
  • the half-bridge center HB is coupled via a coupling capacitor C2 to a first and a second load circuit.
  • the first load circuit comprises the already mentioned lamp La1 and a series resonant circuit comprising an inductance L2 and a capacitor C3.
  • the second load circuit comprises the lamp La2 and a series resonant circuit comprising an inductor L3 and a capacitor C4.
  • a shunt resistor R3 is used to measure the current through the lower switch S3 of the half-bridge. For this purpose, the voltage drop across the resistor R3 is transmitted via an ohmic resistor R4 and a capacitor C4, which serve to averaging, to a device 20 for power measurement. It is used to determine the performance in addition to the current, the known intermediate circuit voltage U zw taken into account.
  • the device 20 for power measurement is coupled on the output side to a control circuit 22, which fulfills two functions. It comprises a threshold value setting device which predefines a threshold value for the set value of the total current through the first L2 and the second inductance L3. This threshold value varies with regard to whether neither of the two lamps La1, La2 has yet ignited or whether one of the two lamps La1, La2 has already ignited. In the event that one of the lamps La1, La2 has already ignited, the threshold value predefined by the control circuit 22 is significantly smaller than in the case in which neither of the two lamps La1, La2 has yet fired.
  • the respective setpoint value specified threshold value is compared with the current actual value in a comparator 24 of the microcontroller 22.
  • the control circuit 22 also serves to predefine the drive generator 18 with a frequency with which the switches S2, S3 of the bridge circuit are to be controlled.
  • the control circuit 22 is in particular designed to further lower the frequency of the signal with which the switches S2, S3 are actuated, after detection of the ignition of one of the discharge lamps La1, La2.
  • the drive generator 18 controls the switches S2, S3 starting with a start frequency. This is gradually lowered, wherein continuously compared via the comparator 24 of the measured via the shunt resistor R3 current to a first threshold becomes. If this threshold value is reached, the ignition process is aborted and started again at the starting frequency. If, however, the lowering of the frequency leads to the ignition of one of the two discharge lamps La1, La2, this is detected by the device 20 for power measurement, whereupon the control circuit 22 provides the comparator 24 with an absolute smaller threshold value. If a further lowering of the frequency with which the drive generator 18 applies the switches S2, S3 to ignite the second discharge lamp, the ignition process is ended. If, however, the lowering of the frequency does not lead to the ignition of the second discharge lamp, the frequency is lowered until the comparator 24 determines that the second, smaller magnitude threshold has been reached.
  • the electronic ballast switches off.
  • a network reset can be used to start a new ignition attempt.
